REINHARDT DAAE, OF PITTSBURGH, PENNSYLVANIA.

GAS PRODUCER.

Application filed January 7, 1920. Serial No. 349,863.

To all whom it may concern:

Be it known that I, REINHARDT DAAE, a citizen of the United States, residing at Pittsburgh, Allegheny County, Pennsylvania, have invented a new and useful lmprovement in Gas Producers, of which the following is a full, clear, and exact description.

The present invention relates to gas producers and has for its principal object a novel form of poker and means for actuating the same. y

. Another object of the present invention is to provide a poker with means for actuating the same in such manner that it Wlll move in overlapping spirals during the operation of the producer to eifett a maximum poking action uniformly throughout the fuel bed.

Still another object of the invention is to provide means for alternately reversing the direction of travel of the poker.

An additional object of the invention is to combinewith the poker a plow adapted to smooth, the-fuel bed after it has been subected to the action of the poker and fill all conditions tending to clog or break the same.

The foregoing and other'objeets, together with their attendant advantages, will be apparent as the invention becomes better understood by reference tothe accompanyingspecification and drawings forming a part thereof, it being premised that changes may be made in the various details and the manner of operation witlnn the scope of the appended clanns without departing irom the spirit of the invention. i

F1gure 8 is an enlarged detail sectional view, of the reversing mechanism forthe poker. V v

Figure 9 is aside view of the construction illustrated in Figure 8, and V Figure 10 is a diagrammatic view representing the travel of the poker.

It has heretofore been proposed to provide gas producers with 'apoker rotatably carried by the cover and adapted, during the production of "a relative movement be tween the cover and the body of the pro-- ducer, to be rotated about its own axis. This causes the poker to-travel in a series of circles which results in a maximum poking action adjacent the central and outer portions of the producer, and a minimum. action in the intermediate portionsof the fuel bed.

It is the object of the present invention to provide means for uniformly poking the entire fuel bed during the operation of the producer. I

In the drawings I have illustrated a producer which may be of any desired construction, preferably comprising a body portion 2 supported in any suitable manner, and provided with a gas outlet 4. Carried by the producerbody is a channel-shaped member 5 forming a water seal for the depending angular flange 6 of the cover 7. According to the present invention, the entire. feeding and poking mechanisms are carried by the cover, thereby making it essential that a relative movement between the body portion and the cover be produced. In the drawings found desirable- For rotating the-cover, itis provided with a projecting rim 8 having a series of teeth9 formed in its outer per1phery to constitute a ring gear. Meshing ducer.

with this gear is a driving rear carried by the Slidit 11 driven from any desired source, not shown.

P Q' th Fine. {56 r l l i lf. tain the cover in its proper position are antifriction rollers 12 and 14, respectively, effec-l tive at substantially right angles to each other for preventing lateral movement ofthe cover and supporting the same for rotation.

The cover is formed with a feed opening,

determined amount of fuel through the chute 19 co-operatihg with the hopper 20.

For operating the fuel feed, the coveris provided with a transverseshaft 21 carrying a bevel gear 22 at its outer end meshing" with a gear 2 1 formed on the channel member 5. Due'to this construction as the cover is rotated, rotation will be imparted tot-he shaft 21 and thence through the bevel gear 25 to the bevel gear 26 on the stub shaft 27l The opposite end of the stub shaft carries a pinion gear 28 meshing with a similar gear 29 on the shaft 30, carrying an adjustable eccentric 31 for the pitman' 32'having a connection 3 1 with one side of the casing'16;

From the foregoing it wi 1 be apparent that as the cover is rotated, the casing 16 will. be oscillated across the feed opening 15 in the cover and about its pivotal mounting 17. By changing the adjustment 31, the amount of travel of the casing may be regulated atwill. V r I The fuel for the'casing 16 is supplied by the sliding trap cut-01f 18, as before described. For actuating this cut-off the shaft 21 may be provided with a supplemental bevel gear 35 meshing with the gear 36 on the shaft 37. This shaft also preferably carries an adjustable eccentric 38 for the pitman 39, one end of which has a pin and slot connection 40 with the pivoted lever 41. The upper end of the lever 41 is bifurcated and carries a pin 42 adapted to engage the notch 44: in the lever 45 pivotally connected at 46 with the sliding trap cut-off. During normal operation of the cover, the sliding cut-off will be actuated by the mechanism described for frictionally transferring fuel from the chute 19 to the casing 16, from which casing it is, in turn, fed into the pro- The stroke'of the sliding cut-off is preferably such that the opening or'pocket therein is never brought into complete alignment with the chute, thus insuring the transfer of the fuel frictionally by the upper surface of the cutoff. I

For preventing clogging and consequent breaking of the apparatus, a yoke 47 is pivota lly connected to the opposite sides of the chute '19 and carries a roller 48 adapted to co-operate with the sliding trap cut-off. Projecting downwardly;from the forward portion of the yoke is an arm 49 adapted to lie under the angular portion 50 of the lever 45. If any of the fuel projects above the pocket in the trap cutoff, it Will elevate the yoke 47 through the roller 48, and thereby disengage the lever 45 from its operating lever 21. is soon as the material 15 properly positioned within the cut-off, the parts will resume their normal positionsand fuel will again be automatically fed to the producer.

To insure rotation of the chute 19 with the casing 16, there may be provided con-' necting pins or bars 51. Also the casing '16 may have a portion 52 of one of its walls inclined to facilitate the feed of'fuel'through the. cover opening, and maybe" provided with an adjustable gate 54 for assisting in the control of the feed' Thecover also carries a poker 55 anda plow 56 with mechanism for actuating the same. The poker is preferablyswingingly mounted in the cover, and providedwith a segmental gear 57 by means of whlch it 62 adapted to be moved into driving engagement with either set of gearing. 'lhe" clutch member 62 is controlled by one end of the bell crank 64: having a pivotal mounting65 on the producer cover, and having its opposite end 66 in engagement with thelever 67 having a pivotal mounting 68. The upper end of the lever 67 carries a weight 69, and this intermediate portionis pro'videdwith an arcuate slot 70 through which the arm 66' passes. Projecting from one side of the lever 67 is an arm 71 adapted to beinte'rmittentlv engaged during the operation'of the producer by one ofthe pins'72 carried by the poker 55; From the foregoing, it will be apparent that after the pokerhas been swung a predetermined distance about its axis in one direction, one ofthe pins 72 will engage the arm 71 and through the lever 67 and bell crank mechanism described, throw the clutch member into engagement with the other set of gearing, thereby changing the direction of movement of the poker; Due to the provision of the weight and'th'e slot, a snap action of the clutch'm'einber' is insured. The gearing is preferably" such that the direction of movement of the poker will be reversed oncefor every four coniplete revolutions of the cover thereby cans revolutions of the cover, so that the spiral path, traversed by the poker, will be automatically varied. By bending the lower portion of the poker, as clearly indicated in- Figure 2 of the drawings, there is exerted a continuous down pressure on the fuel bed up of the fuel bed.

during the operation of the producer, thereby tending. to prevent objectionable opening a poker constructed in the manner described,

, has been found to produce a uniform poking potion throughout the entire body of the uel.

(Jo-operating with the poker 55 is a plow 56 which is preferably formed by two arms adapted to straddlethe poker and connected by the intermediate transverse portion 56 forming a presser foot riding over the fuel bed and filling the openings which may be formed by thepoker. The plow is adapted to slide through a bushing in the cover in bell crank 78.

accordance with thelevel of the fuel within the producer. This movement of the plow is utilized for regulating the rate or amount offuel fed to the producer by means of a segmental projecting member secured to the upper endof the plow. This member co-operates with one arm of a bell crank lever '76, the opposite arm of which is connected by a link 77. with one arm of a similar The other end of the bell crank 78 has an angular portion 79 provided with an opening 80 adapted to receive the arm 81 attached to the pit-man 39 so that the position of the pin and slotconnection withthe lever tl is automatically changed, thereby changing the amount of travel of the slidingtrap cut-off .18.

It will be apparent that the plow 56 is mounted to swing with the poker so that a predetermined relationship exists therebetween.

The advantages of the present invention arise from a construction in which the poker caused to travel in overlapping spirals so that the body of the fuel is uniformly poked.

A. further advantage arises from the provision of a plow co-operating with the poker for filling openings formed in the fuel bed and at the same time controlling the amount of fuel fed to the producer.

A still further and important advantage of the present invention arises from the method of frictionally transferring fuel from the chute to the feed casingby limiting the travel of the sliding cut-off in such manner that the opening or pocket therein is never brought into complete alignment with the chute.
